STEAM-INJ ECTOR.

SPBCIPICA'I'ION forming part of Letters Patent 1\To. 330,682, datev 3. November 17, 1885.

T0 all whom z't may' aoncern:

Be it known that I, JOHN DESMOND, a Citizen of the United Stabes of America, residing ab Toledo, in the county of Lucas and Stute 0f Ohio, have invented certain new and useful Improvements in Steam-Injectors, of whieh the following is aspecifieation, referenee being had therein '00 bhe aceompanying drawings.

My improvement in steam-injectors eonsists in Ehe nove1 arrangemen 0f its chambers C011- neeted by tubes and valves, in bhe peculiar eonstruetion 0f t1he valves and slide-lever for operating thern, and in the combination and arrangement 0f the parts, substantially as hereinafter more fu11y shown and desctibed.

In the accompanying drawings, Figure l is a longitudinal seetional elevabion,Figs. 2, 3, 4, and 5 are detail views, and Fig. 6 is a side elevation, 0f my invention.

In earrying 011i: my invention I Gast integral the metallic chamber A, eomprising several parbibioned-off comparbments, the steam-nozz1e B, the wa'er-supply nozzle C, the Waterout1et nozz1e D, and the overflow-p'ipe' E, and construcb the valve-seafi F with apertures a and b.

The valve F, a cross-seebion of which is shown in Fig. 3, eonsists ot the metallic slide d, conforrned '00 the interior c011t0ur 0f the valve-seat, and having recess e, for reeeption 0f tongue f 0f journal f, the metallie slide d being eaused. t0 register es a valve Wih the steam-port g and apertures a end b (See Fig. l) by means of seid. j0urna1* f, aetuated by means 0f nhe slide-lever G, through which ib projects. The journa1 f is provided wibh the shoulder f (see Fig. 5,) whieh is adapted 130 a eoincidenb recess, f, in it's valve-cha-mher, and is also provided with a corresponding shoulder, f which, in conjunction with the screwcap f", retains the journal actuating the va1ve meehanism in its precise position therein.

The slide-lever G is eonsbructed in seetions, the handle-section being jointed to the longitudinally-slotted section h by means 0f pin h, having an enlarged head projecbed through the guide-bar l of the slolabed section h, the pin h being rigidly eonneeted 150 the handlesection of ohe slide-lever. The slotted 0011- neeion h 0f "ehe slidelever has rigid1y secured thereto bhe valve-rod H, having integral therewith the va1ve H, whieh is adapted as to size 130 fit bhe valve-seat 0f valve-ehamber H and is provided with the transverse apertureH, which is designed 130 register Wih the ingresS-p0rt 11, the egressport j, anti the overflow-pipe E 0f the valve-chamber H The serew-cap I, which robates freely on the valve-rod H, which projeets through a central orifice berein, is threaded ab I, and adapted so a coincident fernale sc rew provided in the interior parb 0f valve-chamber H i The screwcap I is provided With a recess and a shoulder ab I, for reception 0f spim1 spring F, which is esigned to hold ehe screw-cap tightly against the 110110W eap I 0f the slotted seetion h of the slide-lever G, and thus t0 prevent any leakage ab that point, the 110110W cap I arid valve-rod H being rigidly secured together.

The operation is es fo11ows: The valve d is caused te register With bhe steam-port a, thus admibbing steam from the steam-supply pip e through nozz1e B and port g, which finds 01113- leb through steamporb b 111130 chamber K, whieh iS e1osed by serew-cap K, and Whi0h chamber bes a threaded orifice provided in its dividing-wall K, wherein taube K having male screw K* and serew-driver slot: KP, is inserted, Ehe serewdriver s1ot K being designed t0 enable it '00 be tightly serewed into ehe threaded orifice. Steam having been first admitted, es aforesaid, bhereupon simultaneously with the opening of stea'm-porb g and closing of the port b, the slide-valve H is caused to elose the overfiow-pipe E, and hence the steam forces water flowing from a eonduib conneeted With a wel1 through nozzle0 and taube L into charnber M, and bhence through aperture z int-o valve-charnber H, .and the water thereupon passes through aperture j and ascends valve-ehamber F, whereupon the steam-valve d is caused '00 elose the outletport b and open 'he outlet-port a, when the Having thus fu1ly described my invention, what I claim and desire 110 secure by Letters Patent, is-

1. A steam-injeetor consisting of metallic chamber A, eomprising inclosed. compartxments conneeted by tubes, valves d and H, and slide- 1ever G, substantially as shown and deseribed.

2. The combination 0f chamber A, having compartments, connecting-tubes, nozzles, and an overfiow-pipe, Wifih valves F and H, operated by a slide-lever, G, substantially as shown, and f0r the purpose described.

3. The combinabion 0f the valve H, Spira1 spring P, and slide-lever G, having eap 1", for making a t1'ght joint, substantially as shown and described.
